Is there a way to fit local regression through data in Mathematica (equivalent to say "smooth" in ggplot-R)? I've literally spent the last hour searching the internet and documentation centre and I ...

I'm new to mathematica and stack exchange, so any help would be appreciated. I want to plot a bunch of data from text files that contain a lot of extraneous data. I have a hundred files with different ...

I have a device which communicates with the computer through serial. The device waits until it receives the character 'a', and then begins to stream data. I have been able to connect to the device and ...

I would like to elaborate on my previous question Function of arguments given in non-fixed order and a relevant related one Best practice of passing a large number of parameters to functions
I find ...

im trying to use Mathematica in solving of algorithm tasks like this one:
http://poj.org/problem?id=1274
When i was doing those in c/c++ i was able to easily pass input/output in Windows command line ...

Let me first explain the background problem. I'm trying to solve a problem with a projectile motion in 4D such that the position vector is:
$\boldsymbol{r}(t)=\boldsymbol{r}[x(t),y(t),z(t)]$
I have ...

I have the following mathematica code (see below). Is there a way to iterate this approach in such a way to get the p-value results of each test in a list? I would like to get say 1000 p-values for ...

Is there a built-in or fairly elegant way to handle uncertainties in measurement data and/or physical constants?
For instance, the 2010 CODATA for the elementary charge is given as $\mathsf{1.602 176 ...

I used an iterative method to resolve equations, then i plotted the results using ListLinePlot.
Unfortunately, now I need to use some of the data that was plot.
I know the X-coordinate, and need to ...

After quite some struggle, I managed to put up a code that is syntaxically correct. The goal is to find the parameters for a gamma distribution that best match experimental data. The data is a set of ...

I have some data such that I am estimating the time taken by system to reach at some stage. For example. 1 sec to reach at stage 1, 3 seconds to reach at stage 2, 5 seconds to reach at stage 3 and so ...

I'm a physics grad and have been using Mathematica mostly for data visualization. The evaluation part I normally do with C/Python, but I've been wanting to try out Mathematica for these tasks, too.
...

I have a set of data that is just a "random" (generated by me, not by computer) sequence of length 2000 of 1's and (-1)'s. I used it to plot a 1-D random walk where +1 is step up, (-1) is step down, ...

After asking how to get rid of the seasonality of this set of data, I'd like to ask how to investigate the seasonality in data using Mathematica.
Which tool would you use to study seasonality? I.e. ...

I would like to select columns from a table by column name. I tried the solution described here: Data Table Manipulation in Mathematica: Step 2 . I am using Mathematica 10.
(I would write a comment ...

I have the following data set, and wish to track the evolution of the entropy
of each element within the set. I have evaluated the entropy for some elements, but how does one evaluate the entropy of ...

I'm trying to solve a system of nonlinear stochastic differential equation.
It is a discrete nonlinear schrodinger system of n equation, with n independet weiner process.
I'm actually using the Ito ...
